Techniques are disclosed to automatically connect a mobile device to an external display or wireless dock by establishing a bi-directional link between the mobile device and the external display or wireless dock, receiving an image captured by the external display or wireless dock via the bi-directional link by the mobile device, and evaluating the image by the mobile device to verify that the external display or wireless dock is the intended external display or wireless dock with which to connect to the mobile device.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A mobile device operable to automatically connect to an external display or wireless dock, comprising: a wireless interface configured to: establish a bi-directional link with the external display or wireless dock, and receive an image captured by a camera of the external display or wireless dock; and a processor configured to: evaluate the image to verify that the external display or wireless dock is an intended external display or wireless dock with which to connect to the mobile device, and enable streaming of content of a screen of the mobile device to the external display or wireless dock responsive to verification that the external display or wireless dock is the intended external display or wireless dock.
2. The mobile device of claim 1 , wherein the mobile device is a smartphone, tablet or personal computer.
3. The mobile device of claim 2 , further comprising: an application processor; and a touch screen with a touch screen controller interfaced with the application processor and capable of displaying information on the touch screen and external display when connected to the external display.
4. A mobile device operable to automatically connect to an external display or wireless dock, comprising: a wireless interface configured to: establish a bi-directional link with the external display or wireless dock, and send, via the bi-directional link, an expected code word to the external display or wireless dock; a camera embedded with the mobile device to receive bursts of light emitted by the external display or wireless dock, the bursts of light based on the expected code; and a processor configured to: determine whether the received bursts of light represent the expected code word, and in response to determining that the received bursts of light represent the expected code word, automatically connect with the external display or wireless dock.
5. The mobile device of claim 4 , wherein the mobile device is a smartphone, tablet or personal computer.
6. The mobile of device of claim 5 , further comprising: an application processor; and a touch screen with a touch screen controller interfaced with the application processor and capable of displaying information on the touch screen and external display when connected to the external display.
7. An external display device operable to automatically connect to a mobile device, comprising: a wireless interface configured to establish a bi-directional link with the mobile device; a camera embedded with the external display device to capture an image responsive to, at least in part, establishing the bi-directional link with the mobile device, the external display device to send the image to the mobile device via the bi-directional link; and wherein the external display device is configured to receive displayable information from the mobile device based on the mobile device determining that the the external display device is an intended external display device based on the image.
8. The external display device of claim 7 , wherein the mobile device is a smartphone, tablet or personal computer.
9. The external display device of claim 8 , wherein once the external display device is connected to the mobile device, it is configured to accept streaming from the mobile device.
10. The external display device of claim 7 , wherein as long as the bi-directional link is established no further re-identification is required.
11. An external display device operable to automatically connect to a mobile device, comprising: a wireless interface configured to: establish a bi-directional wireless link with the mobile device, and receive, via the bi-directional link an expected code word from the mobile device to associate with the mobile device; and a light emitter adapted to send coded light bursts based on the expected code word, the coded light bursts configured to be received by a camera of the mobile device, wherein the external display device is configured to automatically connect to the mobile device in response to determining, by the mobile device, that the bursts of light correspond to the expected code word.
12. The external display device of claim 11 , wherein the mobile device is a smartphone, tablet or personal computer.
13. The external display device of claim 12 , wherein once the external display device is connected to the mobile device, it is configured to accept streaming from the mobile device.
14. The external display device of claim 11 , wherein as long as the bi-directional wireless link is established, no further re-identification is required.
15. A method to automatically connect a mobile device to an external display or wireless dock, comprising: establishing a bi-directional link between the mobile device and the external display or wireless dock; receiving an image at the mobile device from the external display or wireless dock via the bi-directional link, the image captured by the external display or wireless dock based, at least in part, on establishing the bi-directional link; and evaluating the image by the mobile device to verify that the external display or wireless dock is an intended external display or wireless dock with which to connect to the mobile device, enable streaming of content of a screen of the mobile device responsive to verification that the external display or wireless dock is the intended external display or wireless dock.
16. The mobile device of claim 15 , wherein the mobile device is a smartphone, tablet or personal computer.
17. The method of claim 15 , further comprising using an application processor in the mobile device to evaluate the image and using a touch screen with a touch screen controller interfaced with the application processor which is adapted to simultaneously display information on the touch screen and the external display when connected to the external display.
18. A method to automatically connect a mobile device to an external display or wireless dock, comprising: establishing a bi-directional link between the mobile device and the external display or wireless dock; sending by the mobile device via the bi-directional link an expected code word to the external display or wireless dock; receiving, by a camera embedded within the mobile device, from the external display or wireless dock bursts of light, based, at least in part, on the expected code word; and evaluating, by a processor of the camera, the bursts of light to determine whether the bursts of light represent the expected code word, and, in response to determining that the bursts of light represent the expected code word for an intended wireless display or wireless dock, automatically connecting the external display or wireless dock to the mobile device.
19. The method of claim 18 , wherein the mobile device is a smartphone, tablet or personal computer.
20. The method of claim 18 , comprising simultaneously displaying, by an application processor, information on a touch screen of the mobile device and the external display when connected to the external display.
